Are men running off women from dating? If so, why is that?

After reading many posts and comments on here from different guys and posts and comments from guys on instagram, It seems like they are trying to run off the good women who actually want a long term relationship.
Now first to start with is cheating, I’ve seen a few mention that it’s in a man’s nature to be with multiple women.. where exactly is that stated? Because I’ve also seen men say it’s in a man’s nature to be loyal, so that leads me to think that the first guy is talking out of his ass. Same thing as how “a man is supposed to have sex with as many women as possible” I’m pretty sure that’s not a thing either, more so a game that men think of.
I’ve also seen people refer to a set few as “incel” I’m not really sure what that means, if someone could explain that? And of course the guys who say “what would a man benefit from being in a relationship other than sex” I’ve seen that a lot but then realize that it’s the same guys that go and complain about how they can’t find a women, or how they were rejected by a women they liked. So I assume that they say those things to steer other women away from wanting a relationship because they couldn’t get the girl they wanted?
Please correct me if I am wrong, butt this genuinely confuses me
